Extra accessories required for K?M:



To connect TuneECU with the K?M ECU a custom-built adaptor cable is required (Fig 1)

To make up such a cable,the following components are required: (i) a diagnostic OBDII cable
with a 16-pin socket on the one side and flying  leads on the other (Fig. 2). This cable is commercially
available as an accessory in many OBD-motorsport shops (ii) a 6-pin connector  (Fig.3).



Typical application for the sample connector in Fig.3:

* 2006-2009 Yamaha YZF-R6 Secondary Injector harness (main harness side);
* 2006 Yamaha YZF-R6 Injector harness (sub-harness side);
* Honda CBR600RR Ignition wiring harness;
* See Corsa Technic Motorsport Shop: http://www.corsa-technic.com/
* Item Title: "6-Way Plug Kit (B6AP) Sumitomo type"
* Price: US$2.65 plus Shipping.

Many thanks to Alain for the pictures.

There can occasionally be problems with connecting stability to K?M ECU's, e.g. with running engine.
An improvement can be obtained, if you change the parameters for the virtual COM-port.
The following settings are only one example, which have helped many users.
It is possible these settings will not help all users, however; then some other parameters must be changed.
The following settings are made available coutesy of "Tuning Center Otto Leirer"  from Austria
Once again a big thanks to Otto.


Another Tip, that can possibly help comes from "moto-abruzzo" from the Aprilia forum.
Link the cable shield with the ground pin of the OBD connector.
See the following picture.

Note: the picture shows the connection on pin 5 for Aprilia, K?M uses pin 4 as ground.

Thanks "moto-abruzzo" from the Aprilia-Forum

Another tip from "k?mguy" from the K?M forumThanks k?mguy

To avoid disconnection issues check and fix the following:
Make sure the shield of the USB cable is fixed to the negative of the cable.
See the wire and shield together in the heat shrink in the following picture.

He de-soldered the cable, stripped it back a bit, joined the shield and the negative and soldered it all back
on with some heatshrink around it.

He also fitted a ferrite choke on the cable as you see here:

On his bike Tuneecu disconnected as soon as he started the engine, these 2 mods fixed the issue
and now it stays on no problem.
